Big Data vs. Bad Air

In mid-October 2016, officials from China’s Ministry of Environmental Protection counted five illegal trash-burning sites and hundreds of thousands of vehicles exceeding emission standards in Beijing alone. For the first time since last winter’s pollution high season, city officials issued a yellow air-quality alert, which required shutting down power plants and reining in Beijing’s frenetic factories and road traffic. If this winter is anything like past winters, the city will have to pull out the yellow card again—and may even have to reach for its red card.

How a New Middleman Might Help Balance Electricity Grids

A few years ago almost two thousand bold households on the Danish island of Bornholm joined a surge pricing experiment run by their electricity utility. It was supposed to empower the utility and consumers with a simple, direct market (“The Smartest, Greenest Grid,” IEEE Spectrum, April 2013).

The EU-funded project, called EcoGrid, won widespread buy-in from residents, who could also earn small payoffs when they reduced demand.  Yet researchers reported last year that they could reduce demand by only 1.2 percent of peak load, despite early predictions of up to 20-percent reductions for so-called virtual power plants. The market model was missing something. Continue reading

Ronnie Nader: Ecuador’s One-Man Space Program

Ronnie Nader is practically a one-man space program. Nader, a systems engineer and Ecuador’s only astronaut candidate, completed four years of cosmonaut training in Moscow in 2007, subsequently helped establish Ecuador’s own “vomit comet” zero-gravity training program, and managed the design, construction, launch, and operations of the country’s first two orbiting satellites in 2013.

Robot Cars To Join Formula E Racing

The Formula E electric motor racing series is adding a robotic opening act: autonomous cars will race just before the human-driven race begins. The races, scheduled for the 2016-2017 season, will comprise a parallel championship called ROBORACE.

The robo-cars won’t have the same specifications as the human-driven ones. Free from the burden of meat and safety hardware, the robot cars could have an hours’ endurance, organizers say, which is about double that of last year’s human-driven Formula E cars.
